Analysis:
1. Suppose you had placed a filter paper in a 30% peroxide solution. Using your graph predict how long it would take this disk to rise to the top.
The beset fit line yielded the equation T= 796.33x-1.0357 , revealing that at 30% the time should be approximately 23.5 seconds.
2. Describe how the concentration affects the breakdown rate of hydrogen peroxide.
As the data revealed the greater concentration of hydrogen peroxide results in a lower average time for the disk to rise to the top, which means that oxygen bubbles are produced at a faster rate causing the disk to rise faster. Thus higher concentration results in faster rate of hydrogen peroxide breakdown. This is because the reaction rate is directly dependent on the molarity of the solution and raising the molarity causes a faster reaction.
3. In one paragraph, explain why your hypothesis was supported or not.
The given hypothesis was wrong. Time and concentration are inversely related because the data revealed that as the concentration increased the time decreased. This is because greater concentration results in higher rate of oxygen production, which causes the filter paper to rise faster.
4. Design an experiment to determine the effect of another variable on enzyme activity.
An experiment that testing the effect of temperature on enzyme activity would be best
Effect of Temperature on Enzyme activity
Observe the rate of the same reaction with peroxide concentration held constant and temperature as the variable. Record a similar data and at various temperature ranging from room and going in both directions in increments of 3 degree Celsius.
Conclusion
The purpose of the experiment was to observe the effect of concentration of peroxide on the breakdown of Hydrogen Peroxide into water and oxygen. To achieve this, the rising of filter paper in the solution was measured based on the assumption that faster rates would raise the paper faster. The data revealed this to be true as the best fit curve through the given data (y = 796.33x-1.0357) revealed that they are inversely related. The lower the concentration, the greater the time it will take for the filter paper to rise. Sources of errors include human error while measuring time and preparing concentration but overall the data reflected an accurate trend.
